Attorney General Eric Holder today announced that the Department of Justice will open a civil rights investigation into the death of Eric Garner, the man who was killed in July during the course of an NYPD arrest.

Sean Hannity pointed out tonight on "Hannity" that Holder has no problem investigating a case in which a grand jury has made a clear decision, but when it comes to the violence in Ferguson, he won't look into Michael Brown's stepfather potentially inciting riots.

J. Christian Adams said that this Justice Department has "an enormous hostility toward the police," from Holder prejudging the facts in Ferguson to alleged misconduct by Justice Department lawyers in a case against New Orleans police officers.

Hannity noted that the standards in a civil rights investigation are very high and it must be proven that an officer intentionally tried to violate someone's civil rights, which Adams said will be difficult for the Justice Department to pull off in the Garner case.

As for comments made today by New York Mayor Bill de Blasio, who said that issues between African-Americans and the police are tied to hundreds of years of racism, Adams said we've entered an era when truth doesn't matter.

"There's something bigger going on here. These are attempts to delegitimize ... the system of justice in America by invoking a history that's way in the rearview mirror," Adams said.

"These are folks that want to always blame law and order, the police. They're always on the side of the lawless. It's a bigger battle than just what happened in Ferguson. It's an effort to delegitimize the American system of justice."
